DFX II Series Calibration

IMPORTANT

Gauge calibration should be performed only by those properly trained to service and calibrate Chatillon instruments. Factory service and calibration is available on these instruments and traceable Certiﬁcates of Calibration are provided as requested. Visit www.chatillon.com for a listing of authorized Distributors.

Any changes made to the gauge using the calibration procedure voids the Certiﬁcate of Calibration that accompanied your DFX II Series force gauge. Customers electing to calibrate their gauge do so at their risk and with the understanding that they are effecting the performance of the gauge.

The Calibration Procedure described in the following pages will permit a user to calibrate and re-characterize the loadcell being used. Exercise extreme caution when calibrating any precision instrument.

IMPORTANT

The sensor used in your DFX II Series gauge is temperature sensitive. The gauge should be turned

ON and allowed to acclimate to ambient temperature before normal use and before being calibrated.

A 7 minute “warm-up” period is recommended.

Calibration Setup

A hanger must be used when calibrating the DFX II Series digital force gauge in compression mode. The hanger will ensure that side loading effects are eliminated. Stacking deadweights onto a platen to perform a compression calibration is NOT acceptable.

Shown: a correct compression calibration setup using a hanger ﬁxture.

- 16 -

Procedure

The Chatillon DFX II Series is supplied with a Certiﬁcate of Conformance. The gauge was tested and found to have a measurement accuracy of 0.5% of full scale or better.

Calibration Procedure

The DFX II Series calibration procedure is contained in the gauge ﬁrmware. The calibration is a four point calibration: full scale compression, zero compression, full scale tension, zero tension.

Performing a Tensile Test

The Chatillon DFX II Series may be used to perform a tensile test (also called a pull test). A tensile test causes a pulling effect on the load sensor shaft. The shaft is commonly equipped with a hook adapter or some form of grasping ﬁxture.

Normal Mode Test

Place the gauge into Normal mode by pressing the PEAK key until the mode indicator about the units of measure reads NORM. Normal mode means the gauge will display the real-time load applied to the load sensor shaft. The peak or maximum load is not displayed in Normal mode.

Afﬁx your tensile test adapter (hook, grasping ﬁxture, or the like).

Press the Zero key to zero or tare out the weight of the adapter or ﬁxture attached to the load sensor shaft.

Select Normal Mode

Place the DFX II in Normal mode by pressing the PEAK key until “NORM” is displayed above the units indicator.

Select Units of Measure

Select the UNITS key to specify the units of measure you want displayed.

Afﬁx Test Adapter

Afﬁx your testing adapter to the DFX II load sensor shaft. “Finger-tight” the adapter to the #10-32 threaded shaft.

Press the UNITS key to setup your DFX II to display load in your required units of measurement.

Apply a pull force to the load sensor shaft by pulling on the sample under tester.

In a handheld test, make sure to keep the gauge perpendicular to the centerline of the test sample to avoid side loading effects, e.g. where load is not being applied linearly through the load sensor shaft.

In a tester application, where the gauge is mounted to a test stand, ensure that the center line of the load sensor shaft is aligned directly with the sample on the tester.

Observe the load bargraph on the DFX II gauge to guard against overloads. If the bargraph approached being completely ﬁlled, stop the test immediately to avoid an overload.

While you are pulling the sample, the tensile load indicator will display (opposing arrows).

Once the test is completed, press the PEAK key to observe the maximum tensile load that was achieved during your test.

Peak Tensile Test (T-PK)

This test is performed identically to the Normal Mode Test except the gauge is placed in PEAK mode. Placing the gauge in PEAK mode automatically “freezes and displays” the maximum load achieved during your test.

Apply Pull Force

Apply a pulling force to the sample under test. Observe the load bargraph (ﬁlls from the center towards the “T”) and the Tensile Load Indicator (arrows). The main display will indicate the load being applied to the load sensor shaft using the ﬁxture/adapter.

- 20 -

Zero the DFX II

Select the ZERO key to zero the DFX II and to tare out the weight of the test ﬁxture or adapter.

Observe Load

Read the force result from the display. If you select the PEAK key after you complete your test, the DFX II will display the maximum (Peak) load that was achieved during the test.

Performing a Compression Test

The Chatillon DFX II Series may be used to perform a compression test (also called a push test). A compression test causes a pushing effect on the load sensor shaft. The shaft is commonly equipped with a ﬂat adapter or platen.

Normal Mode Test

Afﬁx your compression test adapter (ﬂat, platen ﬁxture, or the like).

Press the Zero key to zero or tare out the weight of the adapter or ﬁxture attached to the load sensor shaft.

Select Normal Mode

Place the DFX II in Normal mode by pressing the PEAK key until “NORM” is displayed above the units indicator.

Press the UNITS key to setup your DFX II to display load in your required units of measurement.

Apply a pushing force to the load sensor shaft by pushing on the sample under tester.

In a tester application, where the gauge is mounted to a test stand, ensure that the center line of the load sensor shaft is aligned directly with the sample on the tester.

Observe the load bargraph on the DFX II gauge to guard against overloads. If the bargraph approached being completely ﬁlled, stop the test immediately to avoid an overload.

While you are pushing the sample, the compressive load indicator will display (converging arrows).

Once the test is completed, press the PEAK key to observe the maximum compressive load that was achieved during your test.

Peak Compressive Test (C-PK)

Apply Push Force

Apply a pushing force to the sample under test. Observe the load bargraph (ﬁlls from the center towards the “C”) and the Compressive Load Indicator (arrows). The main display will indicate the load being applied to the load sensor shaft using the ﬁxture/ adapter.
